To all whom t may concern:

Be it known that I, Grs'rA WAHLs'rnN, a subject of the King of Sweden, residing at Kvarteret Lennon, Skarsatra, Sweden, have invented certain new and useful Improvements in Driving l/Iiheels for Locomotives, of which the following is a specification.

In locomotives and similarjcarriages it has previously been proposed to use driving w ieels which are shrunk or pressed onto the driving wheel shafts together with or separated 'from the corresponding crank. In case of the driving wheel shaft being journaled inside `the driving wheel, the latter has generally at any point of the spokes the shape oi a crank pin. In embodiments where the driving wheel shaft is journaled outside the driving wheel the latter is generally shrunk or pressed onto the driving wheel shat which at the ends is provided with cranks either by the crank being shrunk or pressed onto the driving wheel shaft or by means of screw-bolts and the like connected with the'saine. In all said constructions it has proved diihcult to place the cranks in correct angular position in relation to cach other and in certain cases such constructions have been an obstacle to the provision et power transmission between the driving mechanism ot the locomotive and the driving wheels incase of the power transn'iitting device consisting of a toothed gearing.

rlhis invention relates to a driving wheel having crank, the wheel being adapted to be advantageously mounted and dismounted and particularly useful in locomotives hav-` ing mechanical power transmission directly to the first driving wheel shaft ot the locomotive. acterizcd by the hub of the driving wheel being extended axially' and formed as a crank integral with the hub by being prefeiabl;7 cast together with the saine.

The accompanying drawing illustrates two embodiments of the invention, the upe per part ci the 'ligure showing the one embodiment and the lower part the other one. In this case the driving wheel 1 is combined with a toothed gearing 2 the slowest rotating shaft 3 of which is located around the driving wheel shaft e and in known manner by means of diaphragm-couplings 5 and 6 transmitting the power through the sleeve 7 to the driving wheel shattG The invention is chiefly charwith the hnb 8. In both embodiments the hub 8 is, according to the invention, provided with an yaxial extension 11 formed as a crank 12. The driving wheel 1 together with the driving shaft 4 is journaled in the bearinglal. between the crank 12 and the part 13 ot the hub. rIhe whole driving wheel or, in case of the same being divided, only the hub of the same kmay either be shrunk, pressed onto or, as shown in the drawing, fastened to the shaft 4i by means of bolts. The driving wheel maybe disinounted by unscrewing the bolts 15 and then the driving wheel,` may be removed from the shaft. essary, especially in case of the gearing having the construction shown in the drawing, since the diaphragms placed inside the driving wheels should be slid axially onto the driving shaft.

What I claim as new and desire .to secure by Letters Patent of the United States is 1. Driving wheel for locomotives and the like, the hub of the wheel being provided with an axial extension and termed as a crank, the extension and the crank being integral with the hub.

2. Driving wheel for locomotives and the like, the hub or the wheel being provided with an axial extension and formed as a crank, the spokes, the hub, the extension and the crank being made in one piece.

This dismounting is nec-` 3. Driving wheel for locomotives and the n like, the hub of the wheel being provided with an axial extension rand formed as a crank, the extension and the crank being integral with the hub, and the extension being formed between the driving wheel proper and the crank as a bearing for the wheel.

In testimony whereof I afiix my signature in presence of two witnesses. l
